WEโREย two days away from Earth, and thereโs good news and thereโs bad news.
The good news is that we havenโt been shot out of the sky. By humans or by aliens trying to harvest our solar energy.
The bad news is there may be no home to return to. Weโve studied the images of Earth (we have telemetry from four full rotations now). Ice covers North America. Europe is buried. There are a few swaths of brown open land in northern Africa. Another in the Middle East. And slightly inland in Australia. We can only see the sunward-facing side of Earth, so we canโt see our world at night, canโt know if lights are still burning down there. Either way, this is a new dark age for humanity.
What are our chances of actually stopping it? I try not to let my pessimism show in front of Emma. She has taken the news hard. I know sheโs worried about her sister and her sisterโs family. I sense the bond is strong between the two of them. Iโm worried about Emma. And my own family. And the rest of the world. I wonder how many are left. It must be agonizing down there, a world running out of habitable land, the ice closing in, the hordes of people fighting to survive. Itโs unimaginable.
After we see the images, we try to keep to our routine. Itโs important to maintain discipline, for me, and for Emmaโs health.
I canโt help stewing over what to do. The situation on Earth definitely necessitates a change in our plans.
Itโs ten a.m. (weโre keeping Eastern Standard Time hours), and Iโm pulling on the exercise bands. Emmaโs pedaling the bike, watching a class lecture from Caltech on adaptive robotics. Harry had the foresight to load
all these college lectures for her benefit. Sheโs used it as a kind of continuing education, and a distraction.
โI think we should contact Earth,โ I say, panting from exertion. She stops pedaling. โWhy?โ
โWe need to know where to land.โ โCanaveralโโ
โMight be a long shot now.โ
This makeshift spacecraft canโt pull off a controlled landing. Weโll need to land in the ocean. Our plan has been to land off the coast of Cape Canaveral. Weโve assumed that NASA would be watching and come and retrieve us. Now Iโm uncertain. The Kennedy Space Center is covered in ice. The entire US is. I have no idea where the NASA personnel evacuated toโor whether theyโre watching for us to touch down. Theyโre not expecting us, and they may not have gotten the broadcast from the comm buoy we deployed.
Once we touch down, weโre definitely going to need some help. I canโt exactly row us to shore. And thatโs only the beginning. Even if the tide somehow carries us in, I canโt drag Emma across a barren, frozen world looking for civilization. We need help or weโre as good as deadโwhether we die up here or down there.
โOkay,โ she says. โWhen?โ
โAs soon as the comm lockout lifts.โ I glance at the time. โToday. Four hours from now.โ
SHE ANDย I sit by the tablet, watching the timer count down until the comm systems come back online. Thirty seconds left.
โHey,โ she says. โIf we canโt make contact, and we just have to land whereverโฆ I want you to leave me.โ
โEmmaโโ
โJust listen. Iโll be safe in the module. Itโll float. Iโll have food, and it has enough power for heat for a while. You can get help and come back for me. Iโll slow you down. You know it.โ
I donโt like that one bit. โWeโll cross that bridge when we come to it.โ The tablet flashes a message.
Comm suite is now online.
Be advised, long distance charges apply.
We both laugh. Nice to see our old crewmates still kept their sense of humor while secretly planning this worst-case contingency.
Weโve already debatedย whomย to call with our first broadcast. If the world is at war, announcing ourselves could put us at risk, make us a target, a pawn to be used or traded, held hostage maybe. There are so many unknowns down there.
We settled on broadcasting on an encrypted NASA channel. The reasons are simple: NASA and its network of private space contractors still have the largest space program. They and the US military are best equipped to rescue us. And Emma and I are both Americansโassuming America still exists.
I start to activate the transmission but hesitate. โYou want to talk, or you want me to?โ
โDoesnโt matter to me. You do it.โ I tap the tablet.
โGoddard flight control, NASA, private space entities, and anyone listening: this is James Sinclair and Emma Matthews, two members of theย Paxย on approach to Earth. We could use some help.โ
THEREโS NO RESPONSE INITIALLY. Or during the first hour. Or the second. Every minute that passes feels like slow motion. We try to stay busy.
I have a plan for when we arrive on Earth. Iโve been working on it, in some fashion, since I woke up in this capsule. It has one purpose: to save Emmaโs life.
โWhat are you thinking?โ Her voice is calm, but I know sheโs nervous.
Sheโs in far more danger on the ground than I am. โI think we broaden the transmission.โ
โEuropeans?โ โYep.โ
The great thing about theย Paxย is that we have access to every imaginable encryption suite, including those used by Roscosmos, ESA, JAXA, CNSA, and a handful of others.
I send a message to the ESA, but thereโs no reply. Four hours later, thereโs still no reply.
โWhat next?โ Emma asks. โWide broadcast?โ โNot yet. Military could pick it up.โ
โOr militias.โ
She thinks the worst has happened. She might be right.
Emmaโs voice is reflective and somber. โYou think we did this?โ โWhat?โ
โYou think our actions out thereโthe fly-by of the artifact and attacking itโyou think it made the artifacts accelerate the Long Winter? Is this part of their counterstrikeโfreezing Earth?โ
Iโve thought about that, but havenโt had the courage to voice it. Iโm glad I donโt know if itโs true. If so, it would gut me. I made the calls out there. If my decisions caused this ice age, and the death of billionsโฆ I donโt know if I could ever recover from it.
โMaybe. I donโt know.โ
She seems to read my mind.
โWe had to do what we did out there, James.โ That makes it a little better. But not much.
Iโve already been tried once for endangering the world. Tried and convicted. Unjustly. Then they sent me into space to save them. I did my best. And I just might have done what they locked me away for.
WE BEDย down in the middle of the module, shoulder-to-shoulder, staring up at the porthole and the stars beyond. Iโm usually the one to pull the shade. Tonight, I peer out, then start taking stock of every last item in the module. My mind mentally assembles the pieces in 3D. I see a rough rendering of what I need, the device that will carry us home.
โWhatโre you thinking about?โ Emma asks softly. โNothing.โ
โYouโre a terrible liar.โ
I smile. โI would think thatโs a good quality.โ
โIt is.โ She pauses. โYouโre thinking about where we should land. And how to build a boat.โ
โYeah. I am.โ
โAnd?โ
โItโs doable.โ I turn to her. โWeโve got the pieces, right here in the capsule. Iโll get you to a hospital. I promise you.โ
โI believe you. I believe if anyone can, you can.โ
We both stare out the porthole then, holding hands, neither saying anything. Iโm glad sheโs here. Glad the crew sent her with meโfor a lot of reasons. Thereโs one reason I never realized until now: Iโll fight harder to save her life than I ever would to save my own.
IN THE MORNING, we broadcast wide, unencrypted. Itโs a gamble, a desperate, last roll of the dice.
A response comes immediately, a gruff male voice.
โMr. Sinclair, this is Colonel Jeffords of the Atlantic Union. Stand by.
Weโre routing your message to the appropriate parties.โ โAtlantic Union?โ Emma whispers.
โIt would seem alliances have been made.โ
I activate the radio again. โCopy that, Colonel. Weโre standing by.โ
The next message comes five minutes later. It isnโt from Jeffords. Itโs another male voice with a European accent, the enunciation too perfect. Definitely someone who learned English as a second language.
โDr. Sinclair. Weโre glad to hear your voice. My name is Sora Nakamura. I represent the Pac Alliance. The Allies welcome you home. Weโre eager to hear your story and to provide assistance. Please verify youโve received our message.โ
Interesting.
Emma turns the microphone off. โWhat do you want to do?โ โWe need to know more.โ
โSuch as?โ
โSuch as who the good guys are.โ
โAnd what if there are no good guys?โ
Sheโs cut to the heart of the issue. Desperate times make devils out of the best of us.
โThen weโll pick whoeverโs most likely to rescue us.โ
I activate the microphone again. โWe read you, Mr. Nakamura.โ
โExcellent. I must say, weโre surprised to hear from you so soon. Our colleagues at JAXA and the CNSA are eager to talk to you. Weโre currently making preparations for a landing site and recovery off the coast of Australia. There are resettlement camps nearby, and the Pac Alliance government is headquartered in Darwin.โ
Thereโs a pause on the comm, as if heโs talking to someone offline. Emma turns off the mic once more. โThe Pac Alliance. A group of
Pacific nations, obviously.โ
Sheโs right. Nakamuraโs reference to the Chinese and Japanese space programs as well as camps in Australia implies a geographic alliance.
โYeah. I bet they crowded into the warm, arid land in Australia. Probably the last habitable zone in the region. Maybe the Japanese, Chinese, and Indians joined forces and moved their people there. Or at least, those they could save.โ
โInteresting,โ Emma says, lost in thought.
I canโt help but speculate about whatโs happened and how the last survivors would organize. Geography and population are the drivers. The Pacific is vast. It covers over thirty percent of the planet. In fact, it covers more area than all of the Earthโs landmasses combined. The Atlantic is much smaller. Itโs roughly half the size of the Pacific. Itโs conceivable that America herded its citizens into its last habitable zones in the US and then transported the rest to northern Africa, where there will be much more survivable land as the world cools. Based on the telescopeโs images, it looks like all of the US is under ice now.
Population is the other factor. Asia has about sixty percent of the worldโs population. Twice as many people as North America, South America, and Africa combined. Asian populations, simply put, need more land to survive. Australia is the logical choice. Itโs hot and dry. There are some hot areas in Southeast Asia, but they lie in the monsoon regions. Theyโll be buried in snow.
If the planet has organized into two spheres, these would be roughly well-matched. And geographically isolated. The question is which we choose.
Thereโs also the region in Iran that isnโt covered in ice, but thereโs been no message from them. Very interesting.
One thingโs certain: there is someone down there to retrieve us. I wonโt have to turn the capsule into a boat, which, frankly, was probably a long shot.
Nakamura comes back on the line.
โIn the interest of time, Dr. Sinclair, we request that you transmit any data you recovered during your mission.โ
With the microphone still off, Emma says, โI donโt like it. They should have gotten the comm bricks already.โ
โThey may have. Maybe theyโre asking about any new data. Or maybe the equipment to read the wireless transmission was lost in the exodus to these last habitable zones. But yeah. I donโt like it either.โ I think for a minute. โTechnically, the data doesnโt reveal much about the course of climate change on Earth. Just the magnitude of the threat.โ
โA threat that is much greater than we imagined. The data confirms that the artifacts are hostile, which implies that the world is in a lot of trouble. The data could spark a war.โ
โOr worsen the war already occurring.โ โTrue.โ
โThereโs another reason not to send it.โ She raises an eyebrow.
โLeverage.โ
โLeverage for what?โ
โOur safety. The data is what we have that they want. Once they have it, they could have no more use for us.โ
Emma looks away. This is outside her comfort zoneโthe double-dealing and distrust. I like that about her. Sheโs a genuine person. Honest. Too goodโtoo pure for the world I fear weโre returning to.
When we make eye contact again, I make my voice even. โThereโs another reason for silence. The artifacts could be listening. Maybe thatโs why weโre still alive. They want to know what we know. And it could be why neither the Atlantic Union nor Pac Alliance has shot us down.โ
โYou want to say no to the Pac Alliance request?โ
โThat might force their handโor cause the artifacts to destroy us.โ โSoโฆโ
โWe buy time.โ
I activate the radio. โCopy that, Pac Alliance. Itโs going to take us some time to get our data suitable for broadcast. Weโll be in touch.โ
Emma bunches her eyebrows. โYou lie a lot better over the radio.โ โLying is easier when you donโt know the person.โ
THERE AREย no further transmissions from Nakamura. I consider that telling. The next transmission comes two hours later, from a familiar voice, one
Iโm relieved to hear.
โJames? Itโs Lawrence Fowler. Please respond if you read me.โ
His voice is like a drink of water to a man whoโs been walking through the desert for a year. I bolt toward it, like a beacon of hope, a sign of an oasis on the horizon.
I tap the transmit button quickly and speak with enthusiasm. โWe read you, Fowler. Itโs great to hear your voice.โ
โLikewise, James. Listen, we need to make plans. Itโs important that we recover you. Thereโve beenโฆ changes here.โ
โCopy that.โ
โWeโve made preparations. Landing coordinates are as follows: the location where you and I first met. Take latitude and add to the degrees the fourth number found on page five of the mission briefing. To the longitude, add to the degrees the seventh number found on the fifteenth page of the mission briefing. Please verify receipt. Do not repeat actual coordinates.โ
I open the digital version of the mission briefing, memorize the numbers, then open a map with GPS. Edgefield Federal Prison lies at 33.76 degrees latitude, -81.92 degrees longitude. I add the numbers from the mission briefing. The location surprises me. Itโs nowhere near the US. Itโs in the Mediterranean, off the coast of Tunisia. I really, really, hope I added that correctly.
โWe copy, Fowler.โ
โPlease cease all communications. Weโll be waiting, James.โ Nakamura responds immediately.
โJames and Emma, we overheard the broadcast from the AU. We certainly appreciate their efforts in providing a safe landing, but be advised, we have already made preparations and feel your safety would be greatly
enhanced by a landing here at our site. We have far more resources and a safer environment here. Please respond and acknowledge that youโre proceeding to our site.โ
Emma leans her head back and exhales. Iโm starting to get stressed too. I activate the radio.
โWe copy, Pac Alliance. As you can see, our vessel is a makeshift escape pod created from theย Pax. Thrust capacity is severely degraded. Weโll know more about our landing approach soon and will be in touch. Weโre also still porting the data for transmission. This is taking a lot of time.โ
โUnderstood, James. If you give us alternative landing coordinates, I assure you that we can secure them and recover you. Your safety and the completion of your mission is our priority.โ
Emma deactivates the radio. โCompletion of our mission?โ โThe data. They want the data.โ
โFowler never asked.โ
โHeโs smarter than that. And he wants us back. If anyone on the ground cares about us, itโs him. Heโs the one who asked me to rescue you. I trust him.โ
โSo do I.โ
โTunisia it is.โ โWhat now?โ
โNow, we rest. And try not to get shot out of the sky before we get home.โ
