Six NASA scientists to emerge from Mars-like habitat

New York, Sep 17 (IANS) Six Nasa scientists, who were living in isolation on a Mars-like habitat in Hawaii since January to determine astronauts’ psychology and requirements during manned space missions, will return to civilization on Sunday.

In January, the crew of four men and two women were quarantined on a vast plain below the summit of the giant volcano Mauna Loa — one of Hawaii’s five volcanoes and the world’s largest.

They remained there for an eight-month simulation activity to gain a better understanding and to get a bit of a feel for how astronauts would respond mentally, physically, and most important, psychologically to a long-term on a manned space mission as well as in an inhospitable environment.

“Long term space travel is absolutely possible,” Laura Lark, specialist at the Hawaii Space Exploration Analog and Simulation (HI-SEAS) project, led by the University of Hawaii at Manoa, was quoted as saying to the on Saturday.

“There are certainly technical challenges to be overcome. There are certainly human factors to be figured out, that’s part of what HI-SEAS is for. But I think that overcoming those challenges is just a matter of effort. We are absolutely capable of it,” Lark added.

Their experiment included everything from being forced to live in the cramped habitat of the dome to having to rely solely on packaged food – and virtually no contact with another living soul.

The atmosphere was as similar as possible to what life on Mars would be. All of the communications the crew could have with the outside world was subjected to a 20-minute delay — the time it takes for signals to get from Mars to the Earth.

The data gathered during this mission can better help in choosing crews that have certain traits and a better chance of doing well during a potential two-to-three year Mars expedition, which would then pave the way for humans settlement in the red planet by around 2030.(IANS)

NASA’s instrument to measure Sun’s energy

  • 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
