In Exactly A Year Our Knowledge Of The Cosmos Will Change Forever. This Is The $10 Billion Reason

In Exactly A Year Our Knowledge Of The Cosmos Will Change Forever. This Is The $10 Billion Reason


In precisely one year—on Tuesday, March 30, 2021—the almost US$10 billion James Webb Space Telescope (JWST or “Webb” for short) will launch on a European Ariane 5 rocket from the Guiana Space Centre to the northwest of Kourou in French Guiana.
The successor to the Hubble Space Telescope, “Webb” will study the solar system, directly image exoplanets, photograph the first galaxies, and explore the mysteries of the origins of the Universe. By detecting infrared light, Webb will be able to look further back in time than any other telescope thus far.
Webb is the most ambitious and complex space science telescope ever constructed, and tantalisingly soon it will the plaything of scientists … or, at least, that’s the plan.
It’s highly possible. Originally conceived in the 1990s and at first expected to launch in 2007, Webb has been beset by delays—the latest being COVID-19—but at the time of writing the massive telescope was safely in its cleanroom at Northrop Grumman in Redondo Beach, California, and March 30, 2020 was still the target date for Webb’s launch. However, there could be an announcement on April 15, 2020about a new schedule.
For now, let’s presume we only have a year left to exist in the pre-Webb era, and get excited about what we’re going to learn about life, the Universe and everything in 2021 and beyond.

You may soon be able to ride to the edge of space from Alaska in a Balloon Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune A company wants to use an advanced balloon to fly customers from Earth’s surface in Alaska to the highest reaches of the planet’s atmosphere. Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune,  The Anchorage Daily News  reported on Sunday. The balloon rides will be manned by a flight crew taking eight passengers in a pressurized capsule suspended beneath a hydrogen balloon the size of a football stadium. Each passenger could pay an estimated $125,000 for a six-hour journey. Mark Lester, CEO of Alaska Aerospace Corp., said the high-altitude rides will be available from Kodiak in a few years and will ...

Committee recommends review of planetary protection policies

Committee recommends review of planetary protection policies WASHINGTON — The NASA Advisory Council has recommended that NASA review its existing planetary protection guidelines to balance the needs of science and exploration, an effort that could set the stage for a similar revision at the international level. The council, during a two-day meeting at NASA Headquarters Dec. 10–11, adopted a recommendation calling on NASA to establish an interdisciplinary committee of experts to review the agency’s current requirements for preventing contamination of other worlds by NASA spacecraft as well as any contamination of the Earth by materials brought back from those worlds. “NASA should establish a multidisciplinary task force of experts from industry, the scientific community, and relevant government agencies, to develop U.S. policies that properly balance the legitimate need to protect against the harmful contamination of the Earth or other celestial bodies with the scientific, social, and e...

Surprise! There's more water on Jupiter than anyone thought

Surprise! There's more water on Jupiter than anyone thought Jupiter  appears to have more water than anyone expected. Newly released data from  NASA's Juno probe shows that water may make up about 0.25% of the molecules in the atmosphere over Jupiter's equator. While that doesn't sound like much, the calculation is based on a prevalence of water's components, hydrogen and oxygen, three times more than at the sun. The new measurements Juno obtained are much higher than a previous mission suggested. The surprise result has scientists delving deep again into results from  NASA's Galileo mission to Jupiter , which obtained drier results in 1995 when engineers deliberately threw the spacecraft into Jupiter's atmosphere. (Galileo was low on fuel and NASA didn't want to take the chance, even if it was a slight one, of the spacecraft accidentally crashing on a potentially habitable icy moon.) Reconciling the results from Galileo and Juno is key for sc...
