NASA's Biggest 2021 Milestones

By: Discovery

From making history on Mars to supersonic aircraft, NASA continues to astound us with science from this past year.

December 28, 2021

2021 was a memorable year for NASA.

Among the many scientific accomplishments for the year, NASA continued preparations to launch the James Webb Space Telescope on Dec. 24 from French Guiana, successfully landed the Perseverance rover on the surface of Mars, and piloted the Ingenuity Mars Helicopter – the first powered, controlled flight on another planet.

NASA welcomed back to Earth the first two sets of commercial crew astronauts to complete expedition missions aboard the International Space Station and launched Crew-3 to the orbiting laboratory.

Here are some of our favorite highlights

  • NASA's Perseverance rover drilled, extracted, and sealed its first rock core into its sampling tube on Mars. The core now is enclosed in an airtight titanium sample tube, making it available for retrieval in the future.
  • Ingenuity became the first aircraft to make a powered, controlled flight on another planet, and recently completed more than 30 minutes of cumulative flight time.
  • NASA’s Parker Solar Probe mission touched the Sun to provide us the first-ever direct observations of the solar atmosphere, the corona, as well as traveling by Venus, where it gave scientists the first complete look at Venus’ orbital dust ring, detected a bright rim around the edge of the planet that may be nightglow, and discovered natural radio emission.
  • The Juno probe provided a fuller picture of how Jupiter’s distinctive and colorful atmospheric features offer clues about the unseen processes below its clouds.
  • NASA’s Chandra X-ray Observatory detected evidence of a possible planet transiting a star in another galaxy, and, for the first time, it detected X-rays from Uranus.
  • NASA’s SpaceX Crew-1 mission successfully completed its first expedition flight, carrying astronauts to and from the space station. The mission included the first spaceport relocation of a Crew Dragon spacecraft. Its nighttime splashdown was the first for a U.S. crew spacecraft since Apollo 8.

Of course, there are already more exciting projects on the way for 2022.

“Next year, NASA will accomplish more daring feats with new discoveries and technological advancements, especially as our Artemis I mission paves the way for future crewed missions to the Moon – and beyond,” said NASA Administrator Bill Nelson.

How 3D Print Building is Changing the Future

Building with 3D printing technology is sparking widespread interest in the construction industry. Besides reducing waste and our impact on the environment, it can speed up construction from weeks, or months, to days. Projects that use simple raw materials like soil, straw, and even salt, can be built in a fraction of the time and cost of traditional construction.
