NASA’s instrument to measure Sun’s energy

For instance, spectral irradiance measurements of the Sun's ultraviolet radiation are critical to understanding the ozone layer -- Earth's natural sunscreen

  • NASA’s new instrument can measure Sun’s incoming energy
  • The instrument is called Total and Spectral Solar Irradiance Sensor (TSIS-1)
  • This can help bring in an energy revolution in future

To continue long-term measurements of the Sun’s incoming energy, NASA has powered on a new instrument installed on the International Space Station (ISS).

Solar energy is one of the biggest energy sources in the world.

The instrument, Total and Spectral solar Irradiance Sensor (TSIS-1), became fully operational with all instruments collecting science data as of this March, NASA said.

“TSIS-1 extends a long data record that helps us understand the Sun’s influence on Earth’s radiation budget, ozone layer, atmospheric circulation, and ecosystems, and the effects that solar variability has on the Earth system and climate change,” said Dong Wu, TSIS-1 project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. TSIS-1 studies the total amount of light energy emitted by the Sun using the Total Irradiance Monitor, one of two sensors onboard.

This sensor’s data will give scientists a better understanding of Earth’s primary energy supply and provide information to help improve models simulating the planet’s climate.

The second onboard sensor, called the Spectral Irradiance Monitor, measures how the Sun’s energy is distributed over the ultraviolet, visible and infrared regions of light. Measuring the distribution of the Sun’s energy is important because each wavelength of light interacts with the Earth’s atmosphere differently.

For instance, spectral irradiance measurements of the Sun’s ultraviolet radiation are critical to understanding the ozone layer — Earth’s natural sunscreen that protects life from harmful radiation.

“All systems are operating within their expected ranges,” said Peter Pilewskie, TSIS-1 lead scientist at the University of Colorado Laboratory for Atmospheric and Space Physics in the US. IANS

NASA Asks American Aerospace Companies to Offer Detailed Ideas for Future Lunar Lander

NASA called the request for input a "major step" forward for its new moon mission, dubbed Artemis

U.S. space agency NASA on Monday asked American aerospace companies to offer detailed ideas for vehicles that could bring two astronauts to the moon by 2024, an American objective that was reconfirmed on the 50th anniversary of the Apollo 11 mission.

NASA called the request for input a “major step” forward for its new moon mission, dubbed Artemis — who in Greek mythology was Apollo’s twin sister.

The space agency published documents explaining in detail what it is looking for in a lunar lander that will bring the two astronauts, one a woman, to the moon’s south pole, where they will stay for six-and-a-half days.

In May, 11 companies including sector mainstays Boeing, Lockheed Martin and Northrop Grumman were picked to lead feasibility studies and develop prototypes by November. Also on the list were newcomers such as Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin.

That same month, Blue Origin unveiled its lander project, Blue Moon.

Now, NASA has provided dozens of pages of specifications that must be met in terms of onboard electronics, communications, and spacesuits.

Any company can reply, not just the 11 shortlisted earlier in the year.

“On the heels of the 50th Anniversary of #Apollo11, we’ve just issued a draft solicitation asking US companies to help us develop the 21st century human landing system that will land the first woman and next man on the Moon in 2024,” NASA chief Jim Bridenstine tweeted.

Behind schedule

After receiving the responses, NASA is expected to make a decision in a matter of months as to which company will build the lander and how.

It will be the equivalent of the lunar module that took Neil Armstrong and Buzz Aldrin to the moon in 1969.

One important difference will be that the lander will berth at a mini moon-orbiting space station, called Gateway, as a kind of port between Earth and the moon. That will allow for the lander to be reused and refueled.

For now, the Artemis mission is behind schedule, mainly due to delays in the construction of the huge, single-use Space Launch System (SLS) rocket, which is primarily being made by Boeing. (VOA)
