Next Mars Mission: Private Company Steps Up for NASA

A fresh deal between NASA and a private space company will send a new weather scout to Mars in 2028. Unlike past missions that NASA ran entirely on its own, this time the agency is handing much of the design and construction work to Relativity Space, a California firm better known for 3D-printing rocket parts. The probe will carry a set of four sensors called Aeolus, named after the Greek wind god, to watch the planet’s dust storms, clouds, winds, and temperatures every day. NASA isn’t just outsourcing for convenience. The agency wants to spend more of its budget on breakthrough science rather than routine satellite building. By teaming with companies that specialize in rapid, low-cost manufacturing, NASA hopes to squeeze more data out of each mission and get those findings into researchers’ hands sooner. Faster climate snapshots could help planners figure out where future robots—or even astronauts—might safely land and survive.The science package itself is a mini-observatory. One sensor keeps an eye on winds and ozone up to 37 miles high. Another slices the air into vertical layers to track temperature and dust. A third snaps pictures of clouds and dust storms across the whole planet every day. The last sensor watches how sunlight warms the ground and how that warmth later escapes back into the atmosphere. Together they should give Mars meteorologists the clearest daily weather report yet. Engineers at NASA’s Ames lab will build the instruments, then bolt them onto Relativity’s rocket for checkout before launch. If all goes well, the stack will leave Earth in 2028 and orbit Mars for at least one Martian year—about 1. 8 Earth years—collecting data. That may sound short, but many NASA orbiters have outlived their original schedules by a decade or more. The MAVEN spacecraft, for instance, worked more than ten years past its one-year warranty before a glitch finally ended its mission. Right now only two NASA satellites still circle Mars: Mars Odyssey, launched in 2001, and the Mars Reconnaissance Orbiter, which arrived in 2006. Both are long past their sell-by dates yet keep working. The new Aeolus mission could follow the same pattern—cheaper to build, quicker to launch, and built to last.
