Я помню тот ванинский порт
И борт парохода угрюмый.
Как шли мы по трапу на борт
В холодные мрачные трюмы.
Над морем стелился туман,
Вздымалась пучина морская,
Вдали нам светил Магадан
Столица колымского края...

Для Маска это минишаттл

Как хорошо что он провел свое выступление в последний день. В твиттере искать новое тяжело, т.к.  Маск, Маск, Маск.....

Как там Роскосмос? Не хочет вступить с ним в долю?

Чего там? Совместный Салют-7 НацКосмоса и ГосКосмоса на лунной орбите нервно курит в сторонке?

там много чего происходит. 
Так то да бурления много, такого количества постов одними ботами (Россия и США создают лунную базу) не создать.

Нац... Гос.... вспомнил про картинку одной красавицы, с такой рекламой

Классический пример, стратегии опережающего развития: пока конкуренты летят на орбиту Луны, Мы сделаем базу на Марсе. "Ставьте перед собой большие цели - по ним тяжелее промазать."

А деньги на базу на Марсе заработаем спекуляциями на биткоине На Марс в ближайшие 25 лет никто не полетит, тем более базу никто не построит. Если только гравицаппу не изобретут.

Satoshi Nonaka now talking about @JAXA_en's reusable rocket programme. Working on a reusable sounding rocket as tech demo #IAC2017

LOX/H2 sounding rocket, 100km target altitude, vertical powered landing, 11.5t total wet mass. Goal 5 flights/2 months. #IAC2017

Prototype engine tests show no damage after 142 firings. Deep throttling too, 21-109%. Designed for easy maintenance. #IAC2019

Progressive flight demos planned, 100m altitude flights this Japanese fiscal year, 5km flights next fiscal year, etc. #IAC2017

Continuing the reusable rocket theme, Shengbao Wu now talking about parachute recovery of launch vehicle stages. #IAC2017

Compares stage recovery methods, considers parachute 'easy' (others might disagree) & efficient. Water or on land landing? #IAC2017

Salt water *not* good for rockets. On land landing needs more impact cushioning, looking at airbags. 3rd option, airborne recovery #IAC2017

Airborne recovery probably only practical for engine modules. Use of parawing parachutes could enable accurate landings #IAC2017

China Academy of Launch Vehicle Tech. working on LV concept w/ reusable 1st stage. Sub-scale tests of parachutes & airbags done #IAC2017

Уж очень студенческий проект

Ducked out of the technical sessions to go to the GNF event with Michael Smart from @UQ_News's hypersonics research group #IAC2017


As an engineer Michael is pained by throwing away beautifully built rockets with every launch... Wants to use scramjets in RLVs #IAC2017


This. Is. SPARTAN! Rocket 1st stage, scramjet 2nd for Mach 5 to 12, rocket 3rd stage (only non-reusable stage). #IAC2017


SPARTAN aiming for the #smallsat launch market. Reduced costs via reusability & aerodynamics (reduced propellant mass) #IAC2017


1st stage reusability via aerodynamics too. Deployable wings & propellors for fly back to launch site #IAC2017


Launch profile rather different to rocket, 1st & 2nd stage stay low because scramjet is air breathing. #IAC2017


Possible launch sites in QLD & SA for launch into high demand polar orbits #IAC2017


"Speaking as an aerodynamicist, it's an ugly duckling." Subscale model of the fly back booster has been flight tested #IAC2017


2nd stage uses the Australian scramjet tech. Unpowered landing (good L/D, would be more maneuverable than the space shuttle) #IAC2017


UQ tech derives from flight tested HIFiRE scramjets. Want to put that R&D investment to use, & soon. #IAC2017


Argues for making use of the atmosphere (for lift & oxidizer), rather than treating it as a nuisance. #IAC2017


Sees Virgin Orbit & RocketLab as main competitors in dedicated #smallsat launch sector. #IAC2017



Key advantage for SPARTAN is almost complete reusability (80%), believe this will give them the edge in launch cost #IAC2017


Latest development, Hypersonix start up aiming to make SPARTAN a reality. Open to additional partners! #IAC2017


Summary slide & Q&A session. Hope that Australian Space Agency will help to bring Australian tech (in general) to market readiness #IAC2017


Q. about alt. air breathing tech (e.g. SABRE). Aimed to keep SPARTAN simple (scramjet has 0 moving parts) & exploit existing tech #IAC2017

In the Generic Tech. for Nano/Pico Platforms session now. 1st STARS, a demo for space elevator relevant tech. #IAC2017


Possible space debris removal applications for this tether technology, too. #IAC2017


Tethers create additional collision avoidance concern (large swept volume), need to minimise deployed mission time (to 8 hours) #IAC2017

A related talk, how to ensure spacecraft disposal at end of mission for large constellations. #IAC2017


Some spacecraft (5-10%?) will fail before EOL, can't dispose of themselves. ASTROSCALE planning retrieval demo. #IAC2017


ELSA-d launch planned 2019, will demo navigation, rendezvous & docking. Want to provide disposal service to constellation operators #IAC2017

Astroscale ready to ship 1st microsatellite, signs agreement with JAXA for 2nd mission

September 21, 2017

After raising a total of US$53 million over the past 3 years, Singapore/Japan startup Astroscale has announced that its first microsatellite, IDEA OSG 1, is ready to be shipped for launch. The microsatellite will be the first step in fulfilling the company's mission to tackle the space debris problem.

IDEA OSG 1 is a 22kg microsatellite co-developed with Japanese corporation OSG, and will be launched by a Soyuz-2, most likely in November or December 2017. The main mission of IDEA OSG 1 will be to monitor small orbital debris, 100μm (0.1mm) or larger, within congested areas of Low Earth Orbit (LEO). It will be the world's first space debris monitoring microsatellite.

The announcement comes approximately a week after Astroscale announced a joint agreement with Japan's space agency JAXA for the firm's second spacecraft, Elsa-d. The spacecraft will be part of the End-of- Life Service by Astroscale (ELSA) program, which is a satellite-retrieval service for retired satellites.

Planned for launch in the first half of 2019, Elsa-d will comprise 2 modules, a Chaser and a Target, which will together detect and retrieve targeted satellites. JAXA, under the agreement, will give Astroscale access to technologies that examine methods to approach and capture space debris. Additionally, JAXA will provide aid to validate the imagery of simulated debris obtained through the ELSA-d on-orbit mission.

The impetus behind Astroscale's mission is the growing number of space debris, which threatens spaceflight safety and destroys the space environment. According to Astroscale, there are 750,000 pieces of small debris which are unable to be tracked from earth, along with 20,000 trackable pieces. The company hopes to contribute to sustainable use of space by tracking and removing debris in a scalable manner.
