The USA Postal Carrier (USPS) dropped information of a marvel area stamp on Tuesday (March 14), revealing it used to be intended to mark the approaching plunge of a tablet wearing the most important pattern ever accumulated from an asteroid. There’s a plan.
“OSIRIS-REx Go back to Earth” Postage Stamp (opens in new tab), with a free up date nonetheless to be introduced later this 12 months, honors NASA’s first challenge to carry again asteroid samples for find out about. The stamp depicts the robot probe’s pattern go back tablet descending beneath a parachute over the Utah barren region, the place the rock and dust-filled container is scheduled to land on September 24, 2023.
“With this new stamp, the U.S. Postal Carrier celebrates NASA’s seven-year OSIRIS-REx challenge to check and map asteroid Bennu and ship a floor pattern to Earth in September 2023. Pattern Scientists will lend a hand us be told extra about how the sun machine shaped, the USPS mentioned in a press free up. (opens in new tab),

OSIRIS-REx is an acronym that stands for: Beginning, Spectral Interpretation, Useful resource Identity and Safety Regolith Explorer. The identify describes the targets of the challenge. “Beginning” refers back to the find out about of historic carbon-rich subject matter accumulated through spacecraft. “Spectral Interpretation” refers to measuring the composition of an asteroid. “Useful resource Identity” is assessing attainable gasoline, oxygen, water and minerals at the asteroid and “Protection” is said to scientists’ calculations of the percentages that Bennu may collide with Earth.
The final a part of the challenge’s identify, REX, is brief for “regolith explorer”, relating to the find out about of the layer of free subject matter at the asteroid’s floor.
introduced from cape canaveral (opens in new tab) On September 8, 2016, the van-sized OSIRIS-REx spacecraft orbited the Solar for a 12 months, till it handed through Earth once more. At that time, it used the planet’s gravity to lend a hand push it towards Bennu, which orbits the Solar however at a special attitude to Earth.
OSIRIS-REx entered orbit across the 1,610-foot-wide (490 m) asteroid in December 2018 and started photographing and mapping its floor to resolve the most efficient websites to gather samples. Scientists have been stunned to seek out from the photographs despatched again through the spacecraft that the asteroid’s floor used to be very other from what they anticipated. Somewhat than being quite clean, it used to be rocky and cratered, so discovering the pattern assortment web page used to be a problem. In the long run, a web page situated in a crater in regards to the dimension of a tennis court docket used to be selected.
The OSIRIS-REx spacecraft didn’t in fact land on Bennu, however as a substitute slowly descended towards its floor and prolonged a robot arm. (opens in new tab), A set instrument on the finish of the arm launched a pant of nitrogen fuel that despatched a cloud of dirt and rocks from the skin of the rocky frame. Greater than two oz of those substances have been captured in a unique container (opens in new tab) into the gathering instrument, which is then close down and retracted into the spacecraft.
Even supposing a couple of oz would possibly appear to be a small quantity, it’s the biggest pattern ever accumulated from an asteroid and the primary asteroid pattern ever accumulated through the USA. Japan prior to now returned asteroid subject matter on its Hayabusa and Hayabusa2 (opens in new tab) Venture.
OSIRIS-REx starts its flight again to Earth on Would possibly 10, 2021. When it will get with regards to the planet this autumn, the pattern go back tablet will break away the bigger spacecraft to land at the floor. The container and go back way is very similar to the process utilized by NASA’s Stardust challenge to land subject matter from a comet in 2006.
“OSIRIS-REx – a collaboration between NASA, the College of Arizona and Lockheed Martin – exemplifies American ingenuity, patience and teamwork,” the USPS mentioned.
The “OSIRIS-REx Go back to Earth” postage stamp can be issued in a panel of 20 Endlessly stamps. Endlessly stamps stay similar in worth to present firstclass mail 1 ounce worth.
