US Cargo Ship Preps to Depart as Crew Studies Bioprinting and Time Perception

Astronauts Luca Parmitano, Andrew Morgan and Nick Hague

A U.S. resupply ship is packed and ready to depart the International Space Station on Tuesday. The Expedition 60 crew is also testing the viability of printing organ-like tissue and exploring the impact of microgravity on time perception today.

NASA astronauts Nick Hague and Christina Koch finished loading and closed the hatches to the Cygnus space freighter from Northrop Grumman today. Hague will lead the robotics activities and command its release from the Canadarm2 on Tuesday at 12:15 p.m. EDT. NASA TV begins its live broadcast of Cygnus’ departure at noon after 109 days at the station.

The crew outfitted Cygnus with the SlingShot Deployer that will eject a series of nanosatellites once the spacecraft reaches a safe distance and a higher altitude from the station. Cygnus will continue orbiting Earth for a few more months of systems tests before it reenters the atmosphere above the Pacific Ocean for a fiery demise.

3-D bioprinting has proven a challenge for scientists on Earth seeking to replicate complex cellular structures. NASA astronaut Andrew Morgan is researching today whether the weightless environment of space may support the fabrication of human organs in space. He set up the station’s new BioFabrication Facility to begin test-printing tissues today. An incubator houses the tissue samples to promote cohesive cellular growth over several weeks.

Flight Engineer Luca Parmitano of the European Space Agency started Monday collecting his blood samples and stowing them in a science freezer for later analysis. Next, he wore virtual reality goggles for an experiment testing his ability to judge the duration of time. Results are collected before, during and after a spaceflight to understand how time perception is affected in space. The impacts could potentially affect space navigation and other mission-oriented tasks.

Commander Alexey Ovchinin tested Russian smoke detectors, conducted a fit check of the Soyuz MS-12 crew ship seats and worked on space biology gear. Cosmonaut Alexander Skvortsov checked out video gear then studied how microgravity affects pain sensation.

19th Global Symposium for Regulators

19th Global Symposium for Regulators

ITU-D 19th Global Symposium for RegulatorsSmall-Satellites, High Altitude Platform Stations (HAPS) and 47 GHz were among the topics discussed at the ITU-D 19th Global Symposium for Regulators in Port Vila, Vanuata, July 9-12.

The background paper ‘Preparing for WRC-19 – Understanding the issues at stake and the impact of decisions to be made’ was among the meeting documents in which 47.0-47.2 GHz is noted as one of the candidate bands for IMT-2020 (International Mobile Telecommunications) and 47.2-47.5 GHz for HAPS.

Regarding Small-Satellites the document says:

At WRC-15, a proposal for a new agenda item for WRC-19 “to consider modifications to the regulatory procedures for notifying satellite networks to accommodate nanosatellite and picosatellite missions” was submitted. WRC-15 decided not to include this as a specific item on the WRC-19 agenda, because it concluded that this matter could best be dealt with by the ITU-R under the standing WRC agenda item 7.

Considering that the size of a satellite is independent of the nature of the service that it is intended to provide, a simplified regulatory regime needs to be developed for non-GSO satellites with short-duration missions, independent of the size of the satellite.

and

Furthermore, it is important to ensure that any satellite radio-frequency operation avoids harmful interference to incumbent and authorized systems and services. The two frequency bands below 1 GHz under consideration for new or upgraded allocation to the SOS (150.05-174 MHz and 400.15-420 MHz) are used for a wide variety of terrestrial and space applications, including for safety of life purposes, and some of these bands are heavily used on a consistent basis. Nevertheless, if new allocations to the SOS in these frequency bands are considered, they should not put undue constraints on any incumbent services.

AMSAT in special 300th edition of ICQ Podcast

AMSAT in special 300th edition of ICQ Podcast

The popular ICQ Amateur Radio Podcast has been running for over 11 years and on August 4, 2019, the ICQ Podcast team released their 300th edition which features an interview with Treasurer and Past President of AMSAT Keith Baker KB1SF.

The first edition of ICQ Podcast was released by Father and Son team Martin Butler M1MRB and Colin Butler M6BOY on July 6, 2008 and since those early days the show has gone from strength to strength.

Released fortnightly on a Sunday at 0900 GMT the ICQ Podcast is available either as an MP3 download or as a YouTube version with optional auto-generated subtitles.

In the 300th edition, Martin Butler M1MRB is joined by Chris Howard M0TCH, Dan Romanchik KB6NU and Frank Howell K4FMH to discuss the latest Amateur / Ham Radio news and this episode’s special feature is the interview with AMSAT’s Keith Baker KB1SF which begins at 1:10:30 into the show.

3-D Bioprinting, Grip Studies on Station May Benefit Earth and Space Systems

3-D Bioprinting, Grip Studies on Station May Benefit Earth and Space Systems

Expedition 60 Flight Engineer Christina Koch of NASA
Expedition 60 Flight Engineer Christina Koch of NASA works with the BioFabrication Facility that will soon be tested for its ability to print organ-like tissues.

The Expedition 60 crewmembers are busy conducting new and advanced science experiments today aboard the International Space Station. A U.S. space freighter will begin its secondary mission after it departs the station on Tuesday.

3-D bioprinting in space may become a viable platform in the future for fabricating human organs. NASA astronaut Christina Koch activated the new BioFabrication Facility in the morning testing its ability to print cells.

Flight Engineer Nick Hague is researching the thermophysical properties of ultra-heated materials in microgravity and installed samples into the Electrostatic Levitation Furnace. He then fueled up the Bioculture System to support the Cell Science-02 bone healing and tissue regeneration study.

Hague and Koch are also training for next week’s robotic release of the Cygnus space freighter after 109 days in space. Cygnus will depart the station Tuesday and eject a set of CubeSats for space research after it reaches a safe distance from the station. The commercial cargo craft will orbit Earth for a few months of systems tests and nanosatellite deployments before its fiery, but safe atmospheric destruction above the Pacific Ocean.

Flight Engineers Andrew Morgan and Luca Parmitano continued to explore how microgravity affects their ability to grip and manipulate objects. The GRIP study, from the European Space Agency, may inform the design of future spacecraft control devices and interfaces.

Commander Alexey Ovchinin and Flight Engineer Alexander Skvortsov continue configuring the new Progress 73 resupply ship and offloading its new cargo. The duo also took turns servicing Russian science hardware and life support systems.
