How often does NASA name a spacecraft after a living person? How often do you get to launch your name into a star? How often does NASA send probes to explore the sun? If your answer to all these questions is NEVER, then you win the honor of adding your name to an SD card bound for the center of our solar system. We’re already on the list with [William Shatner] so we’ll see you there. Submissions for the hot list aboard the Parker Solar Probe close on April 27th, 2018 and it launches in May.
The Parker Solar probe honors living astrophysicist [Eugene Parker] who theorized a great deal about how the sun, and other stars, emit energy. His work has rightly earned him the honor of seeing his name on a sun-bound probe. We even owe the term, “solar wind” to [Parker].
To draw more attention, you can have a few bits aboard this probe dedicated to you or someone you care about by adding your name to their list. Or you can send the name of your greatest enemy into the hottest furnace for millions of miles. Your call.
Even though our sun is the most prominent heavenly body, NASA hasn’t sent a probe to explore it before. They are good about sharing their models and they really know how to write standards for workmanship.

On April 2nd, 2018 a Falcon 9 rocketed skywards towards the International Space Station. The launch itself went off without a hitch, and the Dragon spacecraft delivered its payload of supplies and spare parts. But alongside the usual deliveries, CRS-14 brought a particularly interesting experiment to the International Space Station.
Developed by the University of Surrey, RemoveDEBRIS is a demonstration mission that aims to test a number of techniques for tackling the increasingly serious problem of “space junk”. Earth orbit is filled with old spacecraft and bits of various man-made hardware that have turned some areas of space into a literal minefield. While there have been plenty of ideas floated as to how to handle this growing issue, RemoveDEBRIS will be testing some of these methods under real-world conditions.
The RemoveDEBRIS spacecraft will do this by launching two CubeSats as test targets, which it will then (hopefully) eliminate in a practical demonstration of what’s known as Active Debris Removal (ADR) technology. If successful, these techniques could eventually become standard operating procedure on future missions.

China’s first space station, Tiangong-1, is expected to do an uncontrolled re-entry on April 1st, +/- 4 days, though the error bars vary depending on the source. And no, it’s not the grandest of all April fools jokes. Tiangong means “heavenly palace”, and this portion of the palace is just one step of a larger, permanent installation.
But before detailing just who’ll have to duck when the time comes, as well as how to find it in the night sky while you still can, let’s catch up on China’s space station program and Tiangong-1 in particular.

For this year’s Hackaday Prize, [will.stevens] is growing his own produce and now looks for a way to shield his endeavors from the perils of the British winter. To achieve this, he decided to grow vegetables in sealed containers. Inspired by prior art and backed up by research, his approach is a wild mix of applied laziness on one hand and reckless over-engineering on the other. The sealed containers in this project are PET bottles, chosen for their availability and the produce are carrots, mainly because they can be harvested through the bottle’s mouth. Carrots also feature a high energy density and can provide fibers for plant-based construction materials so [will] deems them ideal space colonist food.
The project is currently in its fourth attempt and somewhere along the road from carrot seeds, dirt and some water in a soda bottle to the current state, the setup sprouted artificial lighting and a CO2 sensor. Fully aware that sealed greenhouses are a proven concept, [will.stevens] provides links to literature one should read before attempting something like this, alongside regular updates on his progress.
With a sensor and LEDs already in place, it is just a matter of time until a raspi will be added. Or we might see the demise of the soil in favor of a hydroponic setup.
In an unusual turn of events, Lockheed Martin has released technical “payload accommodation information” for three of their satellite busses. In layperson’s terms, if you wanted to build a satellite and weren’t sure what guidelines to follow these documents may help you learn if Lockheed Martin has a platform to help you build it.
An opportunity to check out once-confidential information about satellites sounds like a perfect excuse to dig through some juicy documentation, though unfortunately this may not be the bonanza of technical tidbits the Hackaday reader is looking for. Past the slick diagrams of typical satellites in rocket fairings, the three documents in question primarily provide broad guidance. There are notes about maximum power ratings, mass and volume guidelines, available orbits, and the like. Communication bus options are varied; there aren’t 1000BASE-T Ethernet drops but multiply redundant MIL-STD-1553B might come standard, plus telemetry options for analog, serial, and other data sources up to 100 Mbps. Somewhat more usual (compared to your average PIC32 datasheet) are specifications for radiation shielding and it’s effectiveness.
In the press release EVP [Rick Ambrose] says “we’re sharing details about the kinds of payloads we can fly…” and that’s exactly what these documents give us. Physical ballpark and general guidelines about what general types of thing Lockheed has capability to build launch. Hopefully the spirit of openness will lead to the hoped-for increase in space utilization.
If you take Lockheed up on their offer of satellite development, don’t forget to drop us a tip!

Love it or loathe it, launching a sports car into space is a hell of a spectacle, and did a great job at focusing the spotlight on the Falcon Heavy spacecraft. This led [Rogelio] to wonder – would it be possible to snap a photo of Starman from Earth?
[Rogelio] isn’t new to the astrophotography game, possessing a capable twin-telescope rig with star tracking capabilities and chilled CCDs for reducing noise in low-light conditions. Identifying the location of the Tesla Roadster was made easier thanks to NASA JPL tracking the object and providing ephemeris data.
Imaging the Roadster took some commitment – from [Rogelio]’s chosen shooting location, it would only be visible between 3AM and 5:30AM. Initial attempts were unsuccessful, but after staying up all night, giving up wasn’t an option. A return visit days later was similarly hopeless, and scuppered by cloud cover.
It was only after significant analysis that the problem became clear – when calculating the ephemeris of the object on NASA’s website, [Rogelio] had used the standard coordinates instead of the actual imaging location. This created enough error and meant they were looking at the wrong spot. Thanks to the wide field of view of the telescopes, however, after further analysis – Starman was captured, not just in still, but in video!
[Rogelio]’s work is a great example of practical astronomy, and if you’re keen to get involved, why not consider building your own star tracking rig? Video after the break.

About three weeks ago, we reported that a satellite enthusiast in Canada found an unexpected signal among his listening data. It was a satellite, and upon investigation it turned out to be NASA’s IMAGE satellite, presumed dead since a power failure in 2005 interrupted its mission to survey the Earth’s magnetosphere.
This story is old news then, they’ve found IMAGE, now move on. And indeed the initial excitement is past, and you might expect that to be it from the news cycle perspective. But this isn’t the Daily Mail, it’s Hackaday. And because we are interested in the details of stories like these it’s a fascinating read to take a look at NASA’s detailed timeline of the satellite’s discovery and subsequent recovery.
In it we read about the detective work that went into not simply identifying the probable source of the signals, but verifying that it was indeed IMAGE. Then we follow the various NASA personnel as they track the craft and receive telemetry from it. It seems they have a fully functional spacecraft with a fully charged battery reporting for duty, the lost sheep has well and truly returned to the fold!
At the time of writing they are preparing to issue commands to the craft, so with luck by the time you read this they will have resumed full control of it and there will be fresh exciting installments of the saga. Meanwhile you can read our report of the discovery here, and read about a previous satellite brought back from the dead.
