Test flight helps China take a step towards developing space plane

The CASC announced its plans to build a reusable space transport system last year, which would involve building a series of spacecraft that take off and land like regular planes, but can reach any corner of the earth within an hour by flying at least five times the speed of sound at a suborbital altitude.


Friday’s test of an experimental vessel is a step towards the development of a hypersonic vehicle that could reach any corner of the Earth within an hour.

Juno tunes into radio noise triggered by Jupiter’s volcanic moon Io

The Juno Waves instrument “listened” to the radio emissions from Jupiter’s immense magnetic field to find their precise locations.

By listening to the rain of electrons flowing onto Jupiter from its intensely volcanic moon Io, researchers using NASA’s Juno spacecraft have found what triggers the powerful radio emissions within the monster planet’s gigantic magnetic field. The new result sheds light on the behavior of the enormous magnetic fields generated by gas-giant planets like Jupiter.

Jupiter has the largest, most powerful magnetic field of all the planets in our solar system, with a strength at its source about 20000 times stronger than Earth’s. It is buffeted by the , a stream of electrically charged particles and magnetic fields constantly blowing from the Sun. Depending on how hard the solar wind blows, Jupiter’s magnetic field can extend outward as much as two million miles (3.2 million kilometers) toward the Sun and stretch more than 600 million miles (over 965 million kilometers) away from the Sun, as far as Saturn’s orbit.

Report Suggests That Astronauts Shouldn’t get More Than 600 Millisieverts of Radiation Exposure During Their Career. We get 2–3 a Year Down Here on Earth

Universe Today.


Space may be pretty, but it’s dangerous. Astronauts face a much higher dose of ionizing radiation than us Earth-bound folks, and a new report says that NASA’s current guidelines and risk assessment methods are in serious need of an update.

On the surface of the Earth, protected by our extensive magnetic field and layers of thick atmosphere, we experience about 2–3 milliSieverts (mSv) of radiation exposure every year. Even that background level is enough to trigger the occasional cancer growth.

But astronauts, especially those hoping to go on upcoming long-term missions to the Moon and Mars, face a much greater risk due to the high-energy, ionizing radiation constantly soaking every cubic centimeter of space. To mitigate that risk, NASA currently implements a system based on “risk of exposure-induced death” (REID). The space agency estimates the exposure for each astronaut based on their sex, and if the REID exceeds 3%, their spacefaring careers are over.

Teenager to fly with Bezos in inaugural space tourism flight

An 18-year-old is about to become the youngest person in space, rocketing away with an aviation pioneer who will become the oldest at age 82.

Blue Origin announced Thursday that instead of a $28 million auction winner launching with founder Jeff Bezos on Tuesday, the Dutch son of another bidder will be on board. The company said Oliver Daemen will be the first paying customer, but did not disclose the price of his ticket. A family spokesperson said it will be considerably less than the winning bid.

Daemen snagged the fourth and last seat on the space capsule after the auction winner stepped aside because of a scheduling conflict. The offer came in a surprise phone call from Blue Origin last week, he said.

FAA approves Blue Origin launch with Bezos, others aboard

The Federal Aviation Administration (FAA) has officially approved Jeff Bezos Jeffrey (Jeff) Preston BezosFAA approves Blue Origin launch with Bezos, others aboard Richard Branson’s launch changes the way we look at space Branson, Bezos and Musk: A new space race for a new generation MORE ’s highly anticipated spaceflight next week aboard a rocket developed by his aerospace company, Blue Origin.

The license, which was approved by the FAA on Monday and is valid through August, comes as Bezos, along with his brother and two others, are scheduled to launch into space next Tuesday on the New Shepard rocket.

The flight is part of an effort by billionaire-owned technology and transportation companies to make space flight a commercially available experience.

Russia’s space chief wishes his oligarchs invested in space like Branson and Musk

After Sir Richard Branson’s spaceflight this weekend, the leader of Russia’s main space corporation, Roscosmos, offered some kind words about the achievement on Twitter. Dmitry Rogozin called the flight a “landmark” in terms of technology development and expanding the number of humans able to see Earth from space.

Then Rogozin went a step further, lamenting the fact that Russia’s “billionaire oligarchs” spend their money on yachts and vanity projects rather than the development of space technology and increasing humanity’s knowledge of space.

This is a notable comment from Rogozin, who in the past has been critical of one particular billionaire spending his money developing space technology: SpaceX founder Elon Musk. Among other remarks, Rogozin has said that NASA should not get too cocky about its newfound access to space in case SpaceX’s Crew Dragon vehicle “breaks.” He has also said that SpaceX is “gentle” for getting to work in the balmy conditions of South Texas, while Russian engineers and technicians work in the depths of Siberia during the winter.
