China's new 200-day simulation: preparing for Mars?

Anthony Garreffa | Mon, Jul 10 2017 12:44 AM CDT

In its race towards competing with the US and Russia in becoming a space superpower, China has started its new 200-day simulation of living on another planet.

Four students from Beijing University have started a new 200-day isolation experiment called Lunar Palace 365, where they will live on the resources that they would have if they were on the Moon, or Mars. The students will have to generate life-giving oxygen from plants, recycle their own urine into drinkable water, and being conservative with their supplies.

The biggest test of all, will be the psychological side of being isolated from the world. In this world of instant gratification from social media, what will people do with 200 days away from smartphones, their friends and family, and the world at large? The test will show how they will react to not having sunlight for 200 days, which will effect both their physical and mental health.

This isn't the first time a simulation like this has been done, but it is a huge step for China as they are on their path to becoming a competitor to the US and Russia. China wanting to visit the stars is only a good thing, as it will push the US and Russia at the same time. But 200 days away from my phone? I don't know if I could do that.

This weekend, the company marked the second reflight of a Falcon 9 first stage. SpaceX's Falcon 9 rocket successfully launched the BulgariaSat-1 satellite into orbit - the first geostationary communications satellite in Bulgaria's history.

Now, the company has published images of this historic launch.

SpaceX's rocket took off from California's Vandenberg Air Force Base at 1:25 PM Pacific Time, and launched ten satellites to low-Earth orbit for Iridium, a global leader in mobile voice and data satellite communications.

This is the second set of 10 satellites in a series of 75 total satellites that SpaceX will launch for Iridium's next-generation global satellite constellation, Iridium NEXT.

NASA to send a spacecraft into the Sun next year

Lana Jelic | Wed, May 31 2017 12:17 PM CDT

NASA plans to send a spacecraft straight into the Sun next year. The space agency made the announcement during a news conference and a ceremony at the University of Chicago.

NASA to send a spacecraft into the Sun next year 01 | TweakTown.com

The mission begins in August 2018. Since this isn't a journey that a human can take, NASA will send a 10-foot high probe on the historic mission, since this will mark the first time humanity has reached the giant star.

NASA named the probe Parker Solar Probe in honor of astrophysicist Eugene Parker, which is the first time in the space agency's history a space vessel is named after a living person.

The probe will have to withstand substantial radiation and heat never before experienced by a spacecraft. The Parker Solar Probe will have 4.5-inch-thick (11.43 cm) carbon-composite solar shields which will protect the spacecraft from temperatures of around 2,500 Fahrenheit (around 1,380 Celsius).

NASA shows Mars 2020 rover concept

Lana Jelic | Wed, May 24 2017 10:31 AM CDT

NASA has published an artist' concept of the Mars 2020 rover, which should join Opportunity and Curiosity rover on the Red Planet in 2020.

The Mars 2020 rover is intended to investigate an astrobiological relevant ancient environment on Mars, investigate its surface geological processes and history, including the assessment of its past habitability, the possibility of past life on Mars, and a potential for preservation of biosignatures within accessible geological materials.

The Mars 2020 rover introduces a drill that can collect core samples of the most promising rocks and soils and set them aside on the surface of Mars. A future mission could potentially return these samples to Earth.

ISS crew on an urgent spacewalk after equipment failure

Lana Jelic | Tue, May 23 2017 12:33 PM CDT

NASA's astronauts have successfully completed an emergency spacewalk after a key equipment failure on the ISS. The Expedition 51 astronauts had to fix a problem after a computer failure on ISS over the weekend.

Expedition 51 Commander Peggy Whitson and Flight Engineer Jack Fischer of NASA had to change out a multiplexer-demultiplexer (MDM) data relay box on the S0 truss that failed on Saturday morning. The cause of the MDM failure is not known. The data relay box is one of two fully redundant systems housed in the truss that controls the functionality of radiators, solar arrays, cooling loops and other station hardware. The other MDM in the truss is functioning perfectly, providing uninterrupted telemetry routing to the station's systems.

NASA pointed out that the crew was never in any danger.

The company launched a communications satellite that will complete Inmarsat's fifth-generation broadband network. The Inmarsat-5 F4 communications satellite is the heaviest object delivered by the company to space, for now.

Getting the 13,400-lb. (6,100 kilograms) heavy F4 into its intended orbit emptied the Falcon's fuel tanks, leaving no propellant for the landing attempt.

Tesla releases solar roof prices: Cheaper than expected

Lana Jelic | Thu, May 11 2017 1:27 PM CDT

We've heard a lot about Tesla's solar roof tiles products, but the most important piece of information was missing - the price.

The company has now announced the prices, and they are lower than expected. Consumer Reports estimates that a Solar Roof for an average size U.S. home would need to cost less than $24.50 per square foot to be cost-competitive with a regular roof. The cost of Solar Roof is less.

Tesla says that typical homeowner can expect to pay $21.85 per square foot for Solar Roof. The $21.85 per square foot price point was calculated for a roof where 35 percent of the tiles are solar (solar tiles cost more per square foot than non-solar tiles). A 14kWh Powerwall 2 is also an available option.

Solar Roof uses two types of tiles - solar and non-solar. Looking at the roof from street level, the tiles all look the same. Customers can select how many solar tiles they need based on their home's electricity consumption. For example, households that charge an electric vehicle every day may want more solar tiles on their roof.
