NASA has been working hard to prevent the Moon and Mars from human contamination. The agency wants to make sure that it doesn’t mistakenly take organisms or other contaminants from Earth to other planets.

Scientists from United States’ National Aeronautics and Space Administration (NASA) and the German Aerospace Center had launched several fungal and bacterial organisms to the Earth’s stratosphere back in 2019 as part of the MARSBOx experiment. The aim of the experiment was to determine if there is a chance of their survival in Mars. This, because the stratosphere closely resembles the conditions on the Red Planet and is a perfect place to send samples in order to figure out if they’ll survive on Mars. The scientists have now published a paper on their findings, where they have discussed how the spores of black mold survived the trip.

The microorganisms could only live on the surface of Mars temporarily, but the researchers found out that the spored could be relieved after they returned home. The team of scientists placed fungal spores of Aspergillus niger and Salinisphaera shabanensis, Staphylococcus capitis subsp. capitis and Buttiauxella sp. MASE-IM-9 bacterial cells inside the MARSBOx (or Microbes in Atmosphere for Radiation, Survival, and Biological Outcomes Experiment) aluminum container. There were two sample layers inside the container, with the bottom one being shielded from radiation so that NASA can separate the effects of radiation from that of other environmental conditions.

A NASA balloon was was used to carry the container to the stratosphere, where the samples were subject to Martian-like conditions and exposed to UV radiation over a thousand times more than the levels that cause sunburn. “With crewed long-term missions to Mars, we need to know how human-associated microorganisms would survive on the Red Planet, as some may pose a health risk to astronauts. In addition, some microbes could be invaluable for space exploration. They could help us produce food and material supplies independently from Earth, which will be crucial when far away from home,” said Katharina Siems, a team member from the German Aerospace Center.

NASA has been working hard to prevent the Moon and Mars from human contamination. The agency wants to make sure that it doesn’t mistakenly take organisms or other contaminants from Earth to other planets. Apart from that, bringing these contaminants home from could also negatively affect our environment. Siems explained that experiments like the MARSBOx mission “are an important way to help us explore all the implications of space travel on microbial life and how we can drive this knowledge towards space discoveries.”

Twitter Fleets Gets Twemoji Stickers, Some Android Users Can Now Access Twitter Spaces Audio-Chatroom

Published

on


Twitter’s version of Snapchat Stories, called Fleets is now getting a new update that brings Twemoji Stickers tray. The latest feature enables users to add emojis or stickers to Fleets for a better visual appeal. Until now, the Fleets feature on the Twitter Android or iOS app only allowed users to add text over photos or videos. Users could still add emojis if the keyboard had in-built emoji options; however, the latest feature gives access to more 3D-enhanced stickers directly. Moreover, Twitter Spaces, a Clubhouse-inspired audio-chat room is reportedly rolling out to select Android customers.

The Twemoji option for Twitter Fleets is now rolling out to users in Japan and will likely reach other markets in the coming months. The Twemoji button sits next to the text button, as per a photo shared by Twitter. Additionally, the Twemoji currently appears to be limited to iOS users while availability details for Android client remain unclear. Though the feature does not seem to be substantial, it is likely that Twitter would soon add more options like AR filters – similar to what Facebook offers with Stories on Instagram. Notably, the micro-blogging company acquired Chroma Labs last year, the team behind Chroma Stories. The app basically allowed users to add a range of colourful frames and filters to their Stories content.

In another Twitter-related news, some Android users are now getting an early preview of Twitter Spaces, a Clubhouse-inspired voice-based conversation room right on the platform. According to Android Police, Android users who have access cannot start Spaces chatroom yet but can join others and react with emojis. The company is expected to roll out the stable version in March, though the availability may vary according to regions. Twitter Spaces has been available to select iOS users since early February. Twitter Product Designer Maya Patterson had previously explained that the Spaces feature is meant to create a safe space for intimate conversations in public. It will essentially allow users to join or start a voice-based chatroom where they can discuss any topic. Admins will have control over who can speak or join.
