不是一个量级的,本站有chandrayaan-2专贴,可以先了解一下。

月船二号的月球车似乎没有定下来多重,说是30-100千克
西班牙月球车是40千克

因为月船二号是2.6吨,我本以为它也是直接被送入LTO,如此非GSLV-Mk3不可
既然用Mk2,那肯定又得探测器自己先变轨加速到LTO了,如此着陆器干重能有多少呢?

2017.4之前的发射计划
PS:SCAT-SAT是什么卫星?Oceansat-3?

涨价了还是政府采购一直这么贵?
2012年中期的报道里还在说“每一枚PSLV火箭耗用纳税人2160万美元”

Indiacloser to developing its own space shuttle
印度即将开发自己的航天飞机

MUMBAI: India is on the cusp of developingits own reusable space launch vehicle, popularly known as a space shuttle.Isro's 1.5 tonne vehicle resembling an aircraft is provisionally slated to makeits maiden flight towards the end of July or August from the Satish DhawanSpace Centre, Sriharikota.

孟买:印度即将开发自主的可重复使用的航天飞机。印度空间研究组织的这款1.5吨航天飞机将于7月底或8月份在达万航天中心进行首航。

Officially known as the reusable launch vehicle (RLV-TD), it is undergoingfinal preparations at the Vikram Sarabhai Space Centre in Thiruvananthapuram.Its primary role will be to reduce the cost of access to space. The cost ofplacing 1kg of object in space is about $5,000, which scientists are hopingwill come down to about $500 with the RLV.

这款被官方称为可重复使用运载器的航天飞机正在进行最后的准备。其主要任务就是削减进入太空的成本。将1公斤物体送入太空的成本大约是5000美元,科学家希望通过这款航天器成本可降到500美元。

As of now, there are no plans to use it for a manned mission. Speaking to TOI,those connected with the nearly Rs 100-crore project said that the spacecraftwill initially be carried by a single solid rocket booster with nine tonnes ofpropellants.

目前为止,还没有将这种航天飞机用于载人的计划。这个项目成本达10亿卢比,相关人士对本站说刚开始的时候这款航天飞机将借力于一个固体火箭助推器,该助推器含有9吨推进剂。

After lift off, it will zoom to an altitude of 70km and then execute a softlanding in the Bay of Bengal. The duration of thissub-orbital mission is expected to be around 900 seconds.

在发射后,将上升到70公里的高度,然后在孟加拉湾进行软着陆。预计这个亚轨道任务将持续900秒的时间。

visiblemate Kumar•7066•Influencer WordsmithNetworker •blore•1 day agoGood ISRO and I dont agree with people whoare commenting against ISRO's acheivements...
They must never forget that ISRO could landin MARS with Rs 7 per KM....Which none of the other MOST developed countriescould do and that too at first shot!!
Mind you!!

印度空间研究组织干的好,我不赞成那些对该组织持反对意见的人们。。。
不要忘了该组织向星发射探测器时其成本每公里只要7卢比,没有发达国家可以做到这一点。

Godfather Senior•65554•Influencer MovieBuff Wordsmith • visiblemate Kumar•Mumbai•1 day ago
And precisely, at its first attempt, whereeven the most advanced countries failed in their launch after launch !

而且大多数发达国家在第一次发射时都不断的失败了。

India is more than 40 years behind,USA andRussia.Other countries are not interested in space programme.West Europeanshave combined space programme,European satellite landed on comet lastyear.Indians know only coping others with their English knowledge.India is thelargest importer of arms in the world.Why not Indian produce them ?Indiansdepend on MNCs for all modern products,they dont have modern technology.Onlypeople of those countries can invent and innovating new things that arelearning in their own languages.Why not Indians do some thing which is notknown to the rest of the world.

印度在这方面落后于美国和俄罗斯40年。其他国家对空间项目不感兴趣。而欧洲国家有自己的空间项目,欧洲卫星去年登陆在了一颗彗星上。印度只知道通过自己的英语知识来抄袭他人。印度世界上最大的武器进口国,为什么印度自己不生产?印度所有的的现代产品都得依赖跨国企业,因为印度没有自己的技术。一个国家只有靠自己的语言来学习才能发明和创造。为什么印度不这样做呢,真是令人不解。

Buddy you must first know how manysanctions were there on Indiato take its own steps. Now that Indiais a big market and succeeded on its own, world is looking at it. Appreciateand encourage what Indiais doing., just saying Patriotic Bharathiya will not do. Look how USA pats itselfand its people for everything good or bad.

楼上的,你首先得知道印度面临很多制裁,所以要靠自己起步是很困难的。现在印度是个大市场而且靠自己取得了成功,所以全世界现在都在看印度。我很赞赏印度现在的做法,并鼓励印度继续做下去。看看美国是怎样鼓励自己及其人民的吧,不管是好事还是坏事。

All we need is more funding for such projectsand a stop to brain drain.

我们需要做的就是为这样的项目提供资金并停止人才外流。

suhas matiwade•1627•Wordsmith News KingFrequent Flyer • Patriotic Bharatiya•India•1 day ago
not 40 but yes 20 years

美俄在这方面哪有领先印度40年,20年还差不多。

Blue Saturn•2684•Influencer ModeratorWordsmith • suhas matiwade•Location•1 day ago
We started after at least 300 years afterUS and Europe. It is not bad that we are only20 years behind. We shall catch them up soon.

我们的起步至少晚于美欧300年。所以只落后20年不算什么。我们很快就可以赶上。

Yogi Kumar•366•Wordsmith News King FrequentFlyer • Patriotic Bharatiya•Kumar•1 day ago
Still we are doing something, and ifencouraged by the government we can go miles ahead then our counterparts. Asthey say " Try and fail but don't fail to try".

我们依然在努力,如果政府支持的话,我们就可以大大的领先我们的对手。俗话说的好"尝试但失败了,这没关系,但是不要不敢尝试"。

Andy L•11047•Influencer Movie BuffWordsmith • Patriotic Bharatiya•Telanagana•1 day ago
This has to come from universities andprivate companies, innovate and then sell to govt.

应该让大学和私企来做这种事情,等有所创新后,再把这些产品卖给政府

srikanth• Patriotic Bharatiya•1 day ago
If you know the facts, Indians are some ofthe most important contributors in the other so called developed countrieswhere modern technology comes from. It is due to lack of enough willpower andbacking by the Indian govt that no research gets done in India, not dueto lack of talent. If there is not so much corruption and apathy by the govttowards projecting India's image and invest in research and development, nofrigging country could imagine the way our people can put their minds to use.You obviously dont know the facts and are just to blabber what you seesuperficially.

事实是印度人是现代技术发祥地的所谓发达国家最重要的贡献者。由于印度政府缺乏意志力和没有提供足够的支持,所以印度才没有什么研究成果出来,但印度并不缺乏人才。如果政府不腐败,致力于提升印度形象并对科研进行投入的话,那么印度人民将能发挥自己最大的潜力。

Patriotic Bharatiya•41139•Influencer MovieBuff Wordsmith • srikanth•Location•1 day ago
All modern technologies are developed anddeveloping in those countries where education is based on mother tongue,Indianstake use of those known technologies but never develop any any new technology

所有的现代技术都来自于教育基于母语的国家。印度利用了这些已知的技术,但是从来没有研发出新技术来。

jose.varghese14 Varghese•14137•InfluencerWordsmith Networker • Patriotic Bharatiya•1 day ago
You should understand one thing first. India did nothave surplus funds to spend on any R and D. Now that, with the IT companies andother related industries are minting money, and India being one of the top countriesin the world, in IT, we have surplus money and hence the research is going onnow. In due course, Indiawill invent things. Be patient and give our scientists some time. They willmake us proud. Until then, please support their efforts. Using the gravity oftwo planets to launch the Mangalyan is the first time tried in the history..that must be something new right?

首先要明白一件事情。以前的印度并没有多余的资金投入在研发上。现在,随着IT企业以及其他相关企业大赚特赚,也随着印度成为了世界上IT领域最顶级的国家之一,所以我们现在有闲钱,所以印度的研发正在展开。所以印度在未来将有所发明。所以耐心点,给我们科学家一点时间。他们会让我们感到骄傲的。在此之前,你要做的就是支持他们。利用两个星球的重力来发射Mangalyan,这不是历史首次吗?

我可以坐这种航天飞机往返于上海和北京吗,我的好多中国朋友都好嫉妒啊,哈哈哈。

You can take a bullock cart to wherever youwant to go.Stoneage people can never ride a space shuttle.

你可以乘坐牛车去任何你想去的地方,石器时代的人怎么可能知道乘坐航天飞机呢。

确实涨价不少,可能有通胀因素,也可能之前的价格只是火箭本身的费用

而且这还是按美元计价的
2012年中期,1美元兑约55印度卢比,现在接近64
按印度卢比算涨价幅度更是惊人

印度本周四发射通信卫星GSAT-6

腾讯太空讯 8月27日印度空间研究组织ISRO将用GSLV-D6火箭发射通信卫星GSAT-6,这也是GSLV系列火箭第九次向地球同步轨道发射通信卫星,发射地点在ISRO位于斯里赫里戈达岛的萨蒂什·达万航天中心。
此前九次发射三次成功,四次失败,一次部分失败,此次发射也是印度自行研制的低温上面级CUS第三次在GSLV火箭上试验。GSLV是印度自行研发的运载火箭,主要将印度卫星送往地球同步轨道,在地球同步转移轨道(GTO)最大运载能力约2.5吨,近地轨道5吨。此次发射的GSLV-D6火箭高49.1米,整流罩直径3.4米,起飞质量416吨。
通信卫星GSAT-6重约2.1吨,它是印度最新型的通信卫星,将为印度国内提供S波段通信服务。在抵达GTO轨道后,GSAT-6将利用自身推进系统在远地点变轨至地球同步静止轨道,定位在东经83度的位置。GSAT-6卫星的发射将促进印度通信行业的发展。
另外,本月ISRO宣布将在斐济建立卫星测控站,这将使印度在太平洋拥有自主跟踪卫星的能力,此前印度发射卫星测控需依赖美国与澳大利亚的协助。早在2013年印度发射本国火星探测器Mangalyaan时即有航天专家进驻斐济跟踪该卫星,可谓合作由来已久。

ISRO下一步将升级GSLV mk2的GTO运力至2.5t,包括给CUS和仪器舱减重,同时增加(助推器和二级的)vikas引擎的推力。

此举有望帮助Antrix进入商业通讯卫星发射市场。

PS:SCAT-SAT是什么卫星?Oceansat-3?

原计划Ariane V发射的气象卫星INSAT-3DR改用GSLV mk2发射
PS:ISRO这编号是啥规律?GSLV-F06五年前就已经发射了,F05怎么又冒出来了,然后接着又是F09。。。
The next mission, designated as GSLV-F05, is targeted for launch in July 2016 and will carry the 2200 kg INSAT-3DR meteorological satellite.  GSLV-F09 is planned in May 2017 to launch the GSAT-9 satellite.  The prestigious Chandrayaan-2 Mission is designated to be launched by GSLV in 2017-18 time frame.
