International Space Station astronauts will test a new $23 million cabinet to see if it stinks and if it works well - before using it on future missions to the Moon and Mars. The Universal Waste Management System's zero gravity toilet has been better adapted to the female anatomy than the current space toilet.

$23 million toilet on the ISS

While the toilet is equipped with biofilters and its designers predict that after two years it will still have a "sweet smell", the ISS astronauts will perform the first real "sniff test".

Provided everything works well and the astronauts are satisfied with the performance - and smell - of the toilet, a version could be installed in the Orion spacecraft that will bring the first woman and the next man to the surface of the moon in 2024. 

In addition to the toilet, the discontinued Cygnus supply mission also included the crew's belongings, clothing, scientific experiments and even Estee Lauder's cosmetics.

The astronauts will then install the new zero-gravity toilet and all other experiments that will be sent to the station.

The toilet has a lower mass and volume than previous systems, is easier to use, offers more comfort and performance for the crew and treats the urine so that the spacecraft's recycling systems can treat it safely.

If there is no toilet available or the astronaut is on a spacewalk, the astronauts use MAGs, which are diapers that absorb all the waste.

The team that developed the new toilet for NASA participated in a Reddit AMA. They said it would be tested on the ISS before being used on the Orion spacecraft to the moon. 

As for the odor, the team said that the toilet "collects and filters odors with a bacterial odour filter".

Odor control is an important part of the new toilet design. Says the team behind the technology - adding that no one will "smell" it until the astronauts use it.

To allow astronauts to do number one and number two at the same time, the new design seat has been moved forward from its central position.

Once the toilet has been tested by ISS astronauts and all modifications have been made, it could be used by the first woman and the next man to walk on the moon. By 2024, NASA plans to bring people back to the surface of our only natural satellite. They will arrive there with an Orion spacecraft - probably equipped with the UWMS.

Amazon Forest On Fire 2019 (NASA Satellite Data)

With the 2019 fire season in the Amazon approaching its midpoint, scientists using NASA satellites to track fire activity have confirmed an increase in the number and intensity of fires in the Brazilian Amazon in 2019, making it the most active fire year in that region since 2010.
Amazon forest on fire 2019Fire activity in the Amazon varies considerably from year-to-year and month-to-month, driven by changes in economic conditions and climate. 
August 2019 stands out because it has brought a noticeable increase in large, intense, and persistent fires burning along major roads in the central Brazilian Amazon, explained Douglas Morton, chief of the Biospheric Sciences Laboratory at NASA’s Goddard Space Flight Center. 
While drought has played a large role in exacerbating fires in the past, the timing and location of fire detections early in the 2019 dry season are more consistent with land clearing than with regional drought.

“Satellites are often the first to detect fires burning in remot…

Nasa wants to send astronauts to the ISS with SpaceX for the first time

Image
For the first time in ten years, Nasa will again be sending astronauts into space from the United States at the end of May. It will be the first flight with the private space transporter SpaceX.

Premiere for private space shuttleAt the end of May, the US space agency Nasa plans to send astronauts from the USA to the International Space Station ISS for the first time in almost a decade. Nasa astronauts Robert Behnken and Douglas Hurley are to take off on 27 May on board a "CrewDragon" from the private space company SpaceX in a "Falcon 9" rocket from Cape Canaveral spaceport, NASA boss Jim Bridenstine announced on Twitter.
This would be the first time since 2011 that astronauts would be launching to the ISS from the USA - and the first time they would be transported by SpaceX. The company has so far only transported cargo to the ISS. Nasa had decommissioned its own shuttle fleet for cost reasons. The "Atlantis" flew for the last time in July 2011.

NASA captures explosive outburst of dust, ice and gases from comet 46P/Wirtanen, 2019.

SPACE NEWS | NASA | COMET


Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers at the University of Maryland (UMD), in College Park, Maryland, have captured a clear start-to-finish image sequence of an explosive emission of dust, ice and gases during the close approach of comet 46P/Wirtanen in late 2018. 

This is the most complete and detailed observation to date of the formation and dissipation of a naturally-occurring comet outburst. The team members reported their results in the November 22 issue of The Astrophysical Journal Letters.




This second stage was likely caused by the gradual spreading of comet dust from the outburst, which causes the dust cloud to reflect more sunlight overall. After reaching peak brightness, the comet faded gradually over a period of more than two weeks. Because TESS takes detailed, composite images every 30 minutes,…
