Diwata-2 was successfully launched to space on October 29, 2018 at 12:08 GMT+08 from the Tanegashima Space Center in Japan via H-IIA F40 rocket. It is one of the small satellites piggybacked with the main payloads IBUKI-2, also known as GOSAT-2 (JAXA’s Second Greenhouse Gases Observing Satellite), and KhalifaSat, a remote sensing Earth observation satellite developed by the Mohammed bin Rashid Space Centre (MBRSC) in the United Arab Emirates. The other small satellites are the Japanese-made Tenkou, PROITERES-2, Stars-AO, and AUTcube-2. Diwata-2 was inserted into the Sun-Synchronous Orbit at an altitude of 621 km, 43 minutes and 20 seconds after rocket lift-off.

On Oct 29, 2018 at 13:52 GMT+08, initial contact was established between Diwata-2 and the Ground Receiving Station (GRS) located at the Department of Science and Technology Advanced Science and Technology Institute (DOST-ASTI). Short telemetry data was received from the satellite on that day. Diwata-2 was initially tracked using pre-launch orbital parameters. As of 12:40 PM yesterday, October 31, 2018, the GRS can now read the satellite’s status, including vital signs such as fully charged batteries, normal power consumption, and good communication link. Commands were successfully sent and initial check procedures will continue throughout the first week from launch. Initial image captures from the cameras can be expected in the coming days.

Promising NASA research could make Mars missions far more realistic.

This technology will one day allow humans to live and work on Mars—and return to Earth to tell the story.

After a gyroscope failure put the Hubble Space Telescope out of action on October 5, NASA engineers finally see an end to its troubles. They have its backup gyroscope operating within a normal range and expect science operations to resume imminently.

The space telescope entered a low-power safe mode in early October, suspending science operations while engineers here on Earth diagnosed, then attempted to fix the problem.

At maximum efficiency, Hubble uses three gyroscopes for orienting itself to observe a target in the sky. These gyros measure the speed at which the telescope turns, so that it can be aimed accurately.

Human neurons are much larger than those of model organisms mice and rats, so it’s been unclear whether it’s size that makes a difference in our brain’s computational power. Now, in a study appearing October 18 in the journal Cell, researchers show that unlike those of other animals, human neurons employ highly compartmentalized signaling. Human dendrites—the tree-like branching structures that function as neurons’ antennas—process electrical signals differently than dendrites in rodents, the most common model systems for studying neuronal properties.

“The human neuron is basically like a rat neuron, but because it’s so much longer, signals have much farther to travel. The human dendrites thus have a different input-output function” from rats, says senior author Mark Harnett, the Fred and Carole Middleton Career Development Assistant Professor in the Department of Brain and Cognitive Sciences at the Massachusetts Institute of Technology. “Dendrites farther away from the cell body have fewer ion channels, which control signal processing. That was something we absolutely did not expect.”

Harnett, who studies how the biophysical features of neurons shape information processing in the brain, believes our longer, bigger dendritic arbors endow human neurons and their respective circuits with enhanced computational abilities.

ORACLE, Ariz. — They lived for two years and 20 minutes under the glass of a miniature Earth, complete with an ocean, rain forest, desert, grasslands and mangroves. Their air and water were recycled, and they grew the sweet potatoes, rice and other food they needed to survive.

About 1,500 people were invited and some 200 journalists were on hand as the eight original inhabitants of Biosphere 2 left their glass terrarium a quarter-century ago last month in two groups that no longer talked to each other amid the stress of sharing a small space and disputes over how the project should be run. Detractors called the $150 million experiment a failure because additional oxygen was pumped into what was supposed to be a self-sustaining system.

A power struggle in subsequent months led the financial backer, Texas billionaire Edward Bass, to hire investment banker Stephen Bannon, who was later President Trump’s chief strategist, to bring the project back from financial disarray.
