    NASA’s Recently Launched SPHEREx Ejects Dust Cover From Telescope

    The telescope on NASA's SPHEREx observatory

    NASA’s SPHEREx space observatory, which launched into low Earth orbit on March 11, has opened its eyes to the sky. On March 18, the mission team commanded the spacecraft to eject the protective dust cover that shielded the telescope opening. Once science operations begin several weeks from now, SPHEREx (short for Specto-Photometer for the …

    First Stage Sticks the Landing, Second Stage Engine Cuts Off

    After launching NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) observatory and PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites, a first stage booster lands at Vandenberg Space Force Base’s Landing Zone 4 in California.

    The SpaceX Falcon 9 rocket’s first stage has successfully landed at Vandenberg Space Force Base’s Landing Zone 4 in California. Meanwhile, the engine in the Falcon 9’s second stage has cut off.  The next milestone will be when the SPHEREx observatory separates from the rocket’s second stage in about 30 minutes.

    NASA’s SPHEREx: By the Numbers

    NASA's SPHEREx mission will operate in low Earth orbit, detecting hundreds of millions of stars and galaxies and creating the first all-sky spectroscopic survey in the near-infrared. This artist's concept shows the spacecraft and its distinctive conical photon shields, which protect SPHEREx's telescope from infrared light and heat from the Sun and Earth.

    With launch just under 10 minutes away, let’s take a closer look at some important numbers for NASA’s newest space observatory, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer), which will help answer big questions about the early universe, the history of galaxies, and the life-sustaining molecules in planet-forming …
